#Hiya guys,
#I'm Patrick McKenzie (patio11 on HN) and I'm doing this just out of joy of programming puzzles.
#Not really looking for a job at the moment.
#
#I've taken some liberty with standard Ruby programming conventions to make this one file without
#dependencies, for the ease of you actually running it.  It is the result of a very hack-in-progress
#sort of workflow.  A git repo showing my work in stages might be more interesting but, well,
#hard to submit that into the form.

Notes

This is the latest version of an email which I send periodically, offering customers the opportunity to pre-pay for SaaS in return for a discount. The benefits to the SaaS company are better cash flow and reduced churn rate. The benefits to the customer are, well, in the email. This genre of email has produced hundreds of thousands of dollars in pre-pays for some companies I work with, and it rarely requires any more work than this example.

I've put $79 is as a placeholder for the cost of the user's plan. We calculate that for each account, naturally, along with the billing contact's name.

Subject: Save $79 on Appointment Reminder (and get a tax write-off) Formatting: 100% plain text. Gmail automatically links up the central link. From: Patrick McKenzie (Appointment Reminder) patrick@appointmentreminder.org
